Neurofuzzy Control To Address Stochastic Variation In Actuated-Coordinated Systems At Closely-Spaced Intersections, Xiaoli Sun
Doctoral Dissertations
This dissertation documents a method of addressing stochastic variation at closely-spaced signalized intersections using neurofuzzy control. Developed on the conventional actuated-coordinated control system, the neurofuzzy traffic signal control keeps the advantage of the conventional control system. Beyond this, the neurofuzzy signal control coordinates the coordinated phase with one of the non-coordinated phases with no reduction of the "green band" assigned to the coordination along the arterial, reduces variations of traffic signal times in the cycle caused by "early return to green", hence, makes more sufficient utilization of green time at closely-spaced intersections. The neurofuzzy signal control system manages a non-coordinated …
The Mechanical Characterization Of Polymeric Sandwich Materials For Marine Applications, Akawut Siriruk
The Mechanical Characterization Of Polymeric Sandwich Materials For Marine Applications, Akawut Siriruk
Doctoral Dissertations
The growing use of foam core composite sandwich structures has increased considerably in order to reduce the costs of acquisition and maintenance and to improve the operational performance for naval vessels. This study, which is the only one of its kind, focuses on understanding the properties and response of H100 PVC foam and carbon fiber vinyl/ester facing sandwich layups to static, dynamic, and cyclic loads in the presence of sea water, moisture, low temperature, and hydrostatic pressure. Several mechanical properties of both component materials have been identified. The degradations induced by sea water on foam, facing and sandwich were investigated, …

Identifying Methods To Reduce Conflicts Between Automobiles And Bikes In China Using Microsimulation, Terrance Quashun Hill
Masters Theses
With an ever-expanding population and rapid modernization, China is faced with transportation related problems that are both familiar and foreign to the rest of the industrialized world. There is also a large increase in rural-urban migration, resulting in high income disparities and thus diverse transportation needs. While a small but growing percentage of the urban population is adopting automobiles, there are still many people who rely on two-wheel transportation. Engineers in many of the urban cities are facing challenges resulting from an increase in the number of conflicts between various forms of transportation including bicycles, buses, cars, electric bicycles, and …
Classification Of Subwatershed Slopes And Geotechnical Characterization Of Steep Slopes On Reclaimed Mine Lands In East Tennessee, Patrick Hamilton White
Classification Of Subwatershed Slopes And Geotechnical Characterization Of Steep Slopes On Reclaimed Mine Lands In East Tennessee, Patrick Hamilton White
Masters Theses
Mining and logging activity in the Appalachian region create both excessive runoff and sedimentation in local streams and rivers. Also, the Surface Mining Control and Reclamation Act of 1977 led to over compaction of mine spoil which has led to reclaimed mine lands which will not grow economically viable native hardwood forests. In recent years a construction technique known as low compaction grading has allowed for suitable tree growth but stability and sedimentation have not yet been explored. The purpose of this paper is to create a rapid assessment method to classify the characteristics of watersheds based upon their geomorphology, …
The Development And Evaluation Of A Detection Concept To Extend The Red Clearance By Predicting A Red Light Running Event, Jun Xu
Masters Theses
This study focuses on developing and evaluating a detection concept to extend the red clearance by predicting a RLR event. It will dynamically extend the red clearance several seconds when a RLR is predicted to happen otherwise zero. Therefore the time will be used more efficient. In order to evaluate the influence caused by alternative detector positions, a VISSIM network was built up, connecting Econolite ASC/3 controller and ATACID. Due to the lack of realistic data, all the data in this study are fictional, but close to real. Several parameters are artificially modified in order to gain larger RLR occurrence. …
